Post-tonsillectomy pain in children is a difficult problem to manage. We examined the effect of 10% aerosol lidocaine for the post-tonsillectomy analgesia. ASA physical status I or II, between five and thirteen years of age were assigned, in a randomized fashion, into two groups. The Group I, 30 patients, received a total dose of 4 mg/kg of ten percent aerosol lidocaine on the tonsillar beds. Lidocaine was administered at the end of the surgical procedure. The Group II, 30 patients, were not sprayed with lidocaine aerosol. The postoperative pain scores were assessed by a "red and white" visual analoge pain scales (VAPS). VAPS values were obtained at one and eight hours after the operation. Values of one hour after the operation in the group I and II were $20.83{\pm}10.01$ and $34.50{\pm}10.53$, values of eight hours after the operation were $17.33{\pm}9.07$ and $23.5{\pm}11.08$. The post-tonsilectomy pains were significantly lower in the group I compared with the group II at one and eight hours after the operation. In conclusion, 4 mg/kg of ten percent aerosol lidocaine applied directly on the tonsillar beds was showen a superior, immediate post-tonsillectomy analgesic technique.

The use of intravenous patient-controlled analgesia is an effective and increasingly used means of providing postoperative pain relief. Recently a non-electric, disposable and portable infusor, the Baxter $Infusor^{(R)}$, has developed. This delivers not only a continuous drug infusion but can also deliver extradoses of medication on demand. The present study examined the benefits of two kinds of analgesics for pain management in 28 patients undergoing gynecological surgery. One group, 14 patients, received i.v. meperidine 0.5 mg/kg as loading dose in the recovery room and PCA with meperidine 3 mg/kg/day for 3 days only(M group). In the other group, 14 patients, also received i.v. meperidine 0.5 mg/kg as loading dose in the recovery room and PCA meperidine 3 mg/kg/day for 3 days and droperidol 5 mg(MD group). The PCA device used was the Baxter $Infusor^{(R)}$. This unit was fitted with patient control module which had a flow rate 0.5 ml/hr and the lockout time was 15 min. Resulting from the study, the MD patients in the first and second days post-operatively, reported less pain compared with the M group. VAPS(Visual Analogue Pain Scales) values were $3.52{\pm}l.61$ vs. $2.22{\pm}0.69$, $2.38{\pm}1.12$ vs. $1.45{\pm}0.48$ and $1.93{\pm}1.65$ vs. $0.98{\pm}0.36$, respectively pertaining to M and MD groups. In conclusion, the MD group with meperidine and droperidol(mixed regimen) provided more effective postoperative analgesia than M group(meperidine only).
